To @ZZ whom t may concern:

Be it known that we, ALoNzo L. BUR'r'r and JosErH TAYLOR, citizens' of the United Antiskidding Tire-Protectors, .of which the This invention relates td means for protecting pneumatic. tires, such as are commonly used upon.VT automobiles and more particularly 'to/thatclass of protective deljvices which is designed to prevent skidding.

One object of our invention is toprovide an anti-skidding device of the chain 'type which may berreadily. applied to .the tire or detached therefrom and which is pro-` vided with means i'oradjustment to tires-ofI different, diameters. l v

Another object is to provide reinforcing means' which will furnish suilicient rigidity Y at the sides of the links, enabling the main bodyl of each link to be made of verythin 'sheet metal and alsoto furnish continuously connected peripheral strain or tension A members.

Other objects will appear from the fol lowing description in connection with the accompanying drawings, in which-Figure 1, is a side elevation of a portion of an automobile wheel provided with an improved antiskidding tire protector embodying our invention; Fig. 2, is a top plan; view of a portion of the tire protector showing the manner of applying the attaching pliers; Fig. 3, is a cross-section on thel line 3-3 oi Fig. 2; Fig. 4, is an enlarged side elevation of a portion of a terminal section and one form of connecting hook or lathrl Fig. 5,y

is aperspective view of a portion a terminal section and another form ofconnecting latch or hook; and Fig. 6, is a top plan view of o ne of the intermediate sections.

Our antiskidding tire protector is of the chain type in which a series of sections 1, slightly separated and connected into a continuous chain by means of lateral links 3, pivotally secured to studs or rivets 4, projecting upon opposite sides near the ends of each section. Each chain section is semicircular in cross-section and is made of thin sheet metal and provided with integral transverse ribs 6 near each end and an intermediate longitudinal bead 7, which eiied tually prevent slipping or skidding.

each section is preferably made 'of thin sheet'A i metal and for the purpose of reinforcing the same longitudinally. we provide lateral straps 9, extending along eachv side and secured at each end to the studsi. These side straps also perform a very important function as tension members coperating with the links 3 to form continuous uninterrupted peripheral bands to sustain the longitudinal stresses Aexerted .upon the chain and relieving the .studs 4 which merely serve a's connecting rivets. By reason of this construction, as previously pointed out, the shell or vbody of the chain sections may be made of thin sheet metal, the rigidity and strength being augmented by the tension and lreinforcirug; straps 9. y

The terminal' sections are connectedtby latch members'or hooks. In Figs. 2 and t we havzeshown the connecting hooks 12, pivotally mounted in pairs upon the studs a, upon opposite sides of one terminal section and adapted to engage the studs upon the opposite terminal section. The. members of.

each pair of hooks-are'preferably reverselyllength of the chain.v yIt is sometimesdesin able to dispense. with auxiliary adjustingdevices and f or this purpose. we provide latches or connecting hooks 12, such as illustrated in Fig. 5. The shank is threaded and may be screwed more or less into a nut'15, which is swiveled upon the end stud 4 of the tern minal section. In order to =draw the termil` nal sections slightly toward each other for the purpose of engaging or disengaging 'the connecting latch members 12, or 12, we provi-dethe longitudinal.. projections or beads 'i' of said terminal sections with apertures 17, to receive the jaws 18, of a pair of tongs' 20. .v

To prevent injury to the tire from any cut- 110 Sii ice

ting or Wearingaction of the chain, We provide a lining of canvas, leather or sheet .rub-

Aber 21.

chain composed of seyn-cy indrical plates or sections and means .for connecting said sec-frv tions, each *of said seciions/lliaving reinforcing rstraps -extending ylongltudi'n'gglly"upon each side and secured theretojaiid to said j connecting means.-

. 2. A tireprotector comprising a "flexible chainx composed of semicylindrical plates orsections havingstuds at each end upon opposite sides, links pivotally secured to rising a `flexible said studs and connecting adjacent sections, reinforcing straps extending upon each side of said sections and secured at opposite ends to said studs, thereby forming with 'said links continuous tension membersthroughout the length of the chain.'

3. In an anti-sk idding-device for tires, a y

pair of sections, reinforcing straps, extending longitudinally uponeah side thereof and secured thereto and means for uniti-ng said sections comprising a memberv rotatably seep-ted between one osaid sections and the adjyace'nt reinforcing strap, and a device lon -ltudinally adjustable in said rotatable memer for connecting with theadacent section. In testimony whereof We a X our signatures the presenceof two Witnesses.
